MIAMI — The Miami Heat signed free-agent forwards Josh McRoberts and Danny Granger on Monday, and brought back incumbent point guard Mario Chalmers.

All three deals were agreed to previously, but not signed until the Heat had more pieces of their salary-cap puzzle put into place. McRoberts signed a four-year deal that will pay him $5.3 million next season. Chalmers got a two-year deal that will have him earning about $4 million next season. Granger also has a two-year deal and will make just over $1 million next season.

McRoberts averaged 8.5 points, 4.8 rebounds and 4.3 assists for Charlotte last season. Heat President Pat Riley said McRoberts was one of Miami’s “main targets” in free agency.

“We are delighted that this multi-faceted player will help us immensely,” Riley said.

Chalmers has been with Miami for all six of his pro seasons, helping win two championships. He averaged 9.8 points and 4.9 assists last season and shot 38 percent from 3-point range.

Carter: Age is just a number

MEMPHIS, Tenn. — Vince Carter, heading into his 17th NBA season, doesn’t consider age a big issue anymore. The 37-year-old veteran sees a lot of older teams around the league and notes a “very old team” has just won the championship in San Antonio.

So the opportunity to compete for a title drew him to Memphis, even though the Grizzlies have a bunch of 30-somethings in Zach Randolph, Tony Allen and Tayshaun Prince.

Carter said Monday he sees plenty of weapons in Memphis and hopes he can help get the Grizzlies over the hump in the playoffs.

The Grizzlies introduced the veteran Monday after signing him to a reported three-year, $12 million contract. The Grizzlies have reached the playoffs the past four seasons, losing in the Western Conference finals in 2013.

Butler, Augustin to join Pistons

DETROIT — The Detroit Pistons have agreed to deals with free agents Caron Butler and D.J. Augustin, according to a person familiar with the situation.

The team is set to pay Butler $4.5 million next season, with an option for 2015-16. Augustin, a New Orleans native who played collegiately at Texas, will make $6 million over two years.

Detroit has missed the playoffs the last five seasons, and the Pistons recently hired Stan Van Gundy as their new coach and team president. The first order of business this offseason has been to add some perimeter help for the team’s imposing set of big men.

The 6-foot-7 Butler played 56 games last season for Milwaukee and Oklahoma City, averaging 10.5 points and shooting 39 percent from 3-point range.

Augustin was waived by Toronto early last season, but the 26-year-old point guard caught on with Chicago after that and ended up averaging 13.1 points for the season. He shot 40 percent from beyond the arc.

Thunder forward has surgery

OKLAHOMA CITY — Oklahoma City Thunder forward Perry Jones had arthroscopic surgery on his right knee.

The team said Monday in a news release that Jones is expected to be sidelined for four to six weeks before resuming offseason activities. Other details were not revealed.

Jones appeared in 62 games during the past season and averaged 3.5 points and 1.8 rebounds per game.
